  • Just get yourself some GD900 - 30g for about $8, but thanks OP for the post.

    • Opposite of this suggestion, for those who are just building their own system (one system) and do not need quantity, but just quality. I highly recommend Thermal Grizzly Kryonaut after trying it myself. The temperature drop I got on my 4790K compared to the Arctic Silver was so worth it.

      It's only 1 gram though (so it's only good for 2 applications), and more expensive than other pastes, but it's known as the best. If you're going to be overclocking, those few degrees will definitely make a difference.

      • But its twice the price for a few percent improvements.

        • In my opinion, when you buy a PC for personal use, especially one that will be overclocked (which is where good thermal paste is needed anyway, otherwise these are not necessary), you're likely spending upwards of $1500 on the PC at least (saving big money on big parts). So spending an extra $5 or $10 for a thermal paste that's not conductive, gives the best performance, requires no curing time, and doesn't need changing after one or two years; it's definitely worth it.

          • @Fyrelor: If the stuff did anything that useful, then you also posted the specification number that said so. Best themal conductivity from semiconductor to heatsink is hundreds of W/K-m. Show me this magic and many times more expensive thermal compound that does that? Since honest recommendations always say why by citing a relevant spec number.

            No such recommendation will be posted. Those expensive thermal compounds only do what emotions want them to do. What is the difference between them an no thermal compound? A few (single digit) degrees is the heatsink was properly machined and mounted.

            They are marketing to consumers who feel is must be better. Not consumers who learn from facts and numbers. That means profit margins can be obscene. Then most consumers money pays for advertising myths rather than thermal compound.

            What which compound is hundreds of W/K-m?

          You need some perspective. It's <0.5% the cost of a high-end PC. This is one of the cheaper ways to gain a few extra % performance gain at the high end. Diminishing returns etc etc.

        • you won't get a few percent improvement.

          You might get 2 degrees over this, if that.

      • I swapped from kryonaut to mx4 as it kept drying out in my laptop. Apparently it doesn't like high temps. Mx4 doesn't work quite as well but hopefully I don't need to reapply it every few weeks.

        • Wait, is that a figure of speech? Who actually reapplies thermal paste every few weeks?

        • You must have a Mac Pro laptop lol…

        • I'm also a big fan of mx-4. It's reasonably priced, performs close enough to the top tier stuff but is also ultra stable, rated for a minimum 8 years longevity.

        • Thermal compounds even 60 years ago remains just as thermally conductive when wet or dry. It is initially wet so that a heatsink will squeeze out thermal compound everywhere except in microscopic air gaps. Then best thermal conductivity (ie hundreds of W/K-m) results in greatest heat transfer.

      • Thanks for link.
        Grizzly is one of the best of non-conduct thermals.

      • I took it a step further with my laptop and added Thermal Grizzly Conductonaut to an i7-9750H powered Lenovo Y700. Temps went from throttling at 95 degrees to high 70's. Very happy with the result. Regardless of what was used, the default thermal paste was not up to scratch in this particular build.

        • Yeah Thermal Grizzly Conductonaut is a step above Kryonaut, but very risky under the wrong or novice hands. It is highly conductive and has to be applied evenly and thinly, that's why it's used by those who delid on the inside of the die, but risky to do outside as any residue on the motherboard and boom.

      • Ex PC builder here, don’t waste your money on that little bear unless you’re doing overclock your system. It could help to reduce your cpu temp about 3 to 5oC at best, or nothing at all depend on how you apply it and the nature of your cpu. This one dried pretty quick and need to be re-apply within 2 years. Buy yourself the legendary mx4 or nt-h1/h2, you don’t need to think about dry thermal paste for the rest of your system lifetime.

      • You're better off with Coolermaster mastergel in Australia to be honest.

    • GD900 really isn't that great for long term use. Have notice noticeable increases in temps in a few low tier systems that I've used it in after a few months.

  • Probably not the best thermal compound these days, but this is a real blast from the past. Thanks OP.

  • How often should I change that Thermal Compound of my cpu? I havent done it in a few years

    • depends on what you doing and temps , between when hell freezes over or before it fries… 3 years is a figure

    • Usually only if you're changing the cooler/cpu.

    • If it's a low end office machine then probably will never have a need to replace.

      If it's a mid-range to high-end machine with decent heat output, 3ish years would give you optimal cooling and extend the longevity of the silicon.

    • About as often as you should replace your CPU.

  • AS5 is outdated vs stuff like NT-H1, plus it is slightly conductive so might be one to avoid around CPUs/GPUs with SMDs.

  • I remember AS5 being pretty hard to clean off neatly. Stuff like Noctua and Thermalright came off far cleaner. (Metho)

  • What is the best in term of bang for buck now? Don't mind other brand

  • What the hell is this anyway?

  • Spend $90 to save $10 by purchasing a Noctua Cooler that comes with thermal paste

  • Vein or artery?

  • Anyone tried this with cyrogenics?

  • its a bit pseudo science cause of shelf life ….the undisclosed final frontier… basically check your temps after build - unhappy try again still unhappy change goop and see if that effects anything….

  • does look like suppository and grandma would not know it if you left it in the bathroom

  • I've got some Arctic Silver 3 that's 10 years old, the cap has been left on tight…is it still good?

    • goop rots over time, old goop keeps better than new goop so unless you are confident you are buying actual new goop difficult to say - you can either throw it or try it and check temps .

      not happy can reseat or try new goo which is sold without any date and may be just as old lol…

  • This isn't that great.

    The paste that comes from your cooler should be good enough. The difference between brands is negligible.

  • My 2012’s i5-3570k @4.1Ghz (OC from 3.2Ghz) still running strong with H212. Should I get a new thermal paste?

  • Gotta spread it big like the Verge people!

  • I got some Deepcool Z5 thermal paste with 10% silver oxide for my PS4, used it successfully and won't need the rest of the tube. Happy to chuck it in an envelope to someone if they can make use of it.

    • How successful was the thermal paste? I used the same one on my laptop, and the temps were still quite a bit higher than what I expected…

      • I was getting a lot of high fan speeds and after a thorough clean and paste the fan rarely spins up to high speeds. Having said that, it's been a very cool spring and summer in Canberra so no external heat to worry about.
